Ummmmm....I guess I'm guilty of already doing this!
I have an 85 Bronco with a 302 V-8 fuel injection. Gears are 4.56 on stock tires (previous owner was a farmer who used it to pull hay trailers) It's a stick with no OD. So, going 65 MPH he turns about 3200 RPM. Now, this is the second engine in him. I changed the oil twice after installing it. Once for initial break-in and then the second time 1000 miles later. Both times I changed the filter. Since then I haven't touched a thing except for topping off as needed. I use ST dino and it has an ST filter.
So far I have ~135,000 on that engine with no oil or filter changes except for the two I mentioned. No engine noise whatsoever. I've never done a UOA on it though and was thinking about changing the oil and filter before winter hits really hard. Maybe I'll do one then?
Anyway, most of the miles are highway miles >65 but averaging around 75-80MPH. We're talking well over 4000RPM for sustained periods of time. Come to think of it, the only real problem I've had with this truck (other than the original engine having a rod knock at 150,000-which is why I changed it) was the PS. On a road trip to Florida I was asleep and the wife driving. I woke up and she said that the truck was steering a little funny. She said it was a little stiff. I asked how long it had been and she said "ohhh, about the last 200 miles or so." So, we pull over at the next exit and check. Zero PS fluid. Hmm...I take a little closer look. The pressure line off of the side of the pump had BLOWN OFF! Tore the threaded portion right off of the hose. So, we replaced that, topped off the fluid, bled the system and continued on. Haven't had a problem since.
Maybe it's the truck, maybe it's luck but with minimal maintenace this Bronco has more than repaid me for what it cost-with the replacement engine I paid a total of 4500 and have gotten ~200,000 miles outta him.
Anyway, just sharing my story and experience with not maintaining a vehicle.

P.S. I don't change the oil on my 2000 Ford Excursion V-10 either! I do have a bypass filter though!
